ISOFIX mount. Fastening system of children's car seat ISOFIX Fastening of isofix seats

Trips to the car with children have long been not uncommon, even newborn babies parents are in the clinic, then in the village, then by their affairs. Adults in the car are obliged to fasten the safety belts, and how are things going with the kids? Let's see what the law says that the modern industry for the safety of children in the car offers.

The law says ...

In the rules road, namely, it is written: "The transportation of children is allowed subject to ensure their safety, taking into account the design features vehicle" Next explains that in a car equipped with seat belts, children need to be transported in children's retaining devices fastened by seat belts. It is allowed to use other means to fasten the child with stationary safety belts. It is negotiated that on the front seat is allowed to use only a special children's retaining device (chairs, booster). By the way, it is also said about the need to match the restraining device and the growth of the child.

Administrative Code provides for violation of the rules for transporting children in the amount of 3000 rubles. For this money you can buy a car seat, whether it is worth risking the life and health of the child, and even a fine to pay.

Why is the car seat necessarily?

Previously, many were considered, and now they believe that the baby is safer in the hands of the parent. From a psychological point of view, maybe yes: warm, cozy, mom near. But after all, the hands of an adult is not a safety belt, they do not regulate the power of tension, compression with sharp braking. And the child can ride the cabin on the car's salon, because with a sharp braking, shock even on medium speed 50 km / h body weight in such a car increases more than 30 times. Hold your hands even the smallest child will not succeed. That is why the law in all countries with high levels Motor transport development prescribes a special retention device for children under 12 years old. According to the World Health Organization, the use of a special retaining device in the car reduces the possibility of death in an accident for babies by 71%, for older children by 54%. That is why, I took my son from the maternity hospital in car seat-carry, on the winter ice did not want to risk his life.

Types of children's retaining systems

For the safe transportation of children in the car there are car seats, boosters, lining on the stationary safety belt.

Car seats are used for children under the age of 12, but there are large kids, which in 10 years already growing 150 cm or weighing 36 kg, such children can be fastened with regular belts. Read more about children's car seats.

In addition to groups by weight and age, car seats are divided by type of attachment to the car: standard security belts or isofix system (ISOFIX). Well, about the belts are understandable. But the Isofix system (ISOFIX) is a rigid fastening of the chair directly to the car body. But not all cars are equipped with isofixes. You can try to grope between the top and bottom of the rear seat P-shaped loops, welded to the car body. This system began to be used in the early 90s, so it is possible on your car there are no such hinge. If there is no ISOFIX system in your machine, do not be upset, fastening seat belts too good wayTrue, the chair will be slightly riding the seat of the car, but the child who is fastened by internal belts is not going anywhere. Details about the rules of installation and use of car seats, read. Do not be lazy, read. I myself drove the child in the car seat installed behind in the opening between the front seats. Installed from the best motives: to be a good review to the son. According to the traffic police, this is the most safe place To install a car session, a side blow is not so terrible and the front seat will not hit. But here I'm all afraid, kaba in windshield Something did not arrive.

Go ahead. Consider the option of purchasing a booster. Boosters cheaper than car seats, but are suitable only for children weighing from 15 kg (from 5 years) according to some manufacturers, but according to traffic police from 22 kg (from 6 years). In any case, the booster need to try in the store, because its main function to raise the child so that the regular belts of the car legally lay down the child's body, did not touch the neck. Manufacturers go to various marketing moves, combine booster and suitcase for children's things, it seems convenient, but comfort and security may suffer.

If the child grew up from the car session of the group 1-2, then you can buy a booster, not buy a full-fledged car seat, the law does not prohibit it. But remember: the booster loses the safety of the car seat! It attracts only the price of 1000 rubles, and the car seat can be bought from 3000, although the chair may not meet the security standard for such a price, specify this from the seller.

Economy version of the holding device

In the traffic police notes in the safety of passenger children in the car there is no word about using holding devices that simply lead the diagonal belt from the neck of the child, the so-called adapters, although it does not prohibit their use. But on the shelves of shops are full. These are all possible straps, triangles on riveting or on velcro, clamps that are tightened with a shoulder and lumbar strap stripe, not always having a security certificate. And in my opinion, can only be used as an excuse from fine.

Dangerous in general, the product on the crash tests. The head is not fixed, the child can hit his head and about the door, and about front seat, dick under the belts, because It is not firmly pressed to the seat, in general to be in half with strong impact. You can buy such a device only in the most extreme cases, and at least most expensive safety test. And it is better not to risk the child's health at all.

What do I choose myself?

Personally, from the first days of my child's life, I used a car seat-carry, specially bought a stroller 3 in 1, so that the car seat could be removed from the car and put it on the chassis stroller. It looked unusual, people said that it was not a stroller, but a spacecraft. But it is convenient, without unnecessary crackers in the trunk with joint departures, for example, in the park.

After the child grew out of the chair of the group of 0+, acquired a car seat transformer that allows you to change the tilt of the back in the 3rd positions, grows with the child in height and width. Let it be cumbersome, heavy, but not on himself I drive him. But if the child fell asleep on the road, then the tilt of the back should be changed with a slight press of the button, and the son smiles his sleeping dreams, and not sitting. Agree Security + Comfort Good combination of qualities. I regret one thing that when the chair took, I had to take it without a system of Isofix, my german car 1997 was not equipped with such a system. Less than six months I have acquired a modern "Frenchman", it has an ISOFIX fastening on the body and even special extra belt For fastening the children's car seats and the child.

Remember!

If on board your car a child: pay it to transport special attention, Use a special retaining device, especially since the price ranges allow you to buy it and low income. And do not break the traffic rules, do not expose the child and danger yourself.

Many car enthusiasts facing the term ISOFIX do not know what it is and why it is necessary. In this article we will try to close this gap in knowledge. Here you will learn what isofix is \u200b\u200bin the car, why it is necessary, as well as what is its advantages and disadvantages. If you are planning to buy a car, this information will allow you to do right choice, ensure security and avoid traffic violations.

According to the requirements of the rules of the road, the transportation of children in the passenger vehicle until it is used only with the use of special chairs. At the same time, the chairs should ensure the safety of a minor passenger at any emergency situations.

What does ISOFIX fasteners look like

Many manufacturers are engaged in the release of such devices, but the diversity of models and fastening methods has become more negative factor. The fact is that the use of various modifications of the car seat led to frequent errors during their installations. As a result, the children suffered even with minor accidents.

This was the reason for the emergence of a single international standard of rigid fastenings of children's car seats directly to the machine housing. This standard was introduced by the ISO International Institute and was called ISOFIX or ISO Fix.

In addition to ISOFIX, there are alternative standards for fastening a car seat. For example, in the US, the standard is quite popular Latch., and in Canada - UAS..

How to install an armchair with an ISOFIX fastening

Due to the simple design of the fasteners, it was possible to minimize the number of errors when installing a car seat for children. In essence, Isofix is \u200b\u200btwo brackets that are attached directly to the car body. The standard place of their installation is the space between the back and the seat of the passenger rear armchairs.

Installing a chair with ISOFIX fastening

To install the car seat, it is necessary to simply direct it from the brackets to the brackets and snap into the list of clamps. It is almost impossible to make a mistake in such operations, and the reliability of fixation is quite high.

There are also modifications of children's car seats with additional attachment points. Manufacturers argue that such models provide more high degree Child protection.

• Modifications with retractable (telescopic) stubborn leg. Such an emphasis allows you to ensure the impossibility of moving the chair forward in front blows, however, it creates some inconvenience during operation.
• Models with anchor mountwhich have an additional point of fixation using a special belt with a carbine. The strap bracket can be behind the head restraint of the seat or on the floor of the luggage compartment. Such a modification is considered more convenient and no less reliable. Almost all new cars are completed with the ISOFIX system specifically.

It should be noted that most of the children's car seats with the ISOFIX fastening system can also be fixed using conventional car belts. This is useful if the chair needs to be used in a car that is not equipped with an appropriate fastening.

What are the car seats with the fastening of Isofix

Isofix fastening is used for attaching car seats designed for the weight of the child up to 18 kg. These are the so-called group 0+ and group 1.

Car seat with ISOFIX mounting of the group 0+ (left) and 1 (right)

Car seats of group 0+ used for newborns and children weighing up to 13 kg. This design is a set of two main elements - directly carrying seats (crackers) and a base having an isofix type mount. The main advantage of such modifications is the ability to conveniently endure even a sleeping child. Just put a chair on the base, pressed and the safety of the trip was provided. The minuses of such a system traditionally include increased cost, and the base, and the carrying itself have a fairly high price.

Car seats Group 1 are used for weight 9-18 kg. In essence, this is a traditional chair with a standard fastening embedded in its lower part. There are no special design differences, but simplicity allows us to provide reliable fixation and safety.

Also on sale appeared and combined car seats Groups 0 + / 1which can be used for any child weighing up to 18 kg. Such modifications can be installed both during the movement and against it. In this case, the fastening of isofix is \u200b\u200bused mainly exclusively for group 0+. Separate models have a corporate bowl system (up to 180 degrees), allowing to simplify the placement of the child or disembarking it.

Some minuses fastening isofix

The main disadvantage, as already noted, is a weight limit. If the mass of the child is more than 18 kg, it is technically impossible to ensure reliable fastening of the chair during emergency shock loads due to a certain strength of the structural elements.

Some difficulties cause and differences in the design of the passenger seats of the car. Different form of the back, head restraints, differences in size and other factors complicate the use of standard isofix fasteners.

In addition, this chair is comfortable and necessary! Your children sitting in this car chair will not "manage" and disturb you. Why chose exactly isofix (ISOFIX)? This invention is not the only one in its own way. Attempts to do something like that were before, but this invention is the most comfortable and high quality. Not in vain because since 2005 it is precisely it is mounted in all cars.

Video on the fastening of Isofix (ISOFIX)

What criteria chose Isofix?

Before buying a system, you need to check whether your car is equipped with it. If not, you can safely go buy it. Since 2006, all new cars are already equipped with appropriate fasteners. If a isofix system In the car is not provided, then it will be necessary to mount it.

On the rear seat (It happens that in the front), where the chair is installed, there are two grooves. Them appearance: Wide plastic grooves covered with plugs. These plugs are necessarily removed and hiding into a special gluke. If you take this not so seriously, the plugs can lose.

There are fasteners that are built into it, they are called "crocodiles". If you do not need car baby chair - They are hiding under the back. It is necessary to pull them out, remove the protective caps. Mounting into guides are inserted, the chair is moving forward (during this can be heard a click). At the top there is a belt, it is necessary to shift it through the back and fix in the mount (it should be on the wrong sofa or in the trunk - depending on the manufacturer).

In some models of the car there is a stubborn leg (along with the belt or without it). If you have this leg, you will need to adjust it to a little: you need a certain tilt and height.

How to remove Isofix?

You can do it without difficulty. Each attachment (the above "crocodiles") has a lock-latch that helps to avoid popping the fastening. To remove the car chair, you just need to press a button that can unlock the lock, as a result, the guides come out of the grooves. And the belt (call it else anchor) is unfastened. To avoid breakdowns of "crocodiles", they are simply covered with special caps and hide everything in the same glove box, and so that the dust and every garbage can fall into the grooves, plug them.

What do you need to know: all isofix systems Sold in the configuration. But still it is worth remembering that the seat will withstand not only the weight of children, but also the weight of the chair, so it is worth avoiding different loads. But there are fathers who are often traveling by car, and with them they, for sure, will want to take a child. Some drivers advise to take a small pad with them, which will help to avoid unpleasant dents on the seat.

We hope that you will not have any problems with installation or removal of the chair. Remember that by reading the recommendations, you must first try to secure the car chair and - necessarily! - Remove it, and after that you will go all "like oil". Therefore, you have successful to install the system Isofix., smaller difficult moments and as many positive emotions as possible during a trip with children in the car!

What is ISOFIX?

Let's start with a banal. ISOFIX is a system of hard attachment of car seat to the car body. ISOFIX is an international standard for all car manufacturers and children's car seats. It minimizes the likelihood of an error when installing a car seat and improves protective properties. The main purpose, after all, is to eliminate the ability to install the chair incorrectly (up to 70% of installations occurs with errors). After all, here you just need to correctly send the brackets and snap the locks on the brackets of the opposite part in the car.

Isofix is \u200b\u200btwo salads (2 brackets) at the base of the car seat, which with the help of special rods are snapped around the bracket in the car located between the back and the seat of the automotive chairs. Almost always in a place of place, equipped with brackets for the installation of a children's car seat, ISOFIX are located at the right and left of the sofa (although there are exceptions).
To explain in detail the snap-down system and the ISOFIX device in car seats and the car will not, because On the Internet, it is full of such information, and its practical value in terms of the choice of car seats for its Chad is extremely small.

What car seats apply isofix?

Now important. Isofix is \u200b\u200ba fastening used in groups of 0+ and 1, as well as in children's car seats - combinations of these groups. Those. For children weighing up to 18 kg (about 3-3.5 years old). And only in chairs in which the child is fixed with internal straps.
EVERYTHING. List of exhaustive And, as I already wrote, hard standardized.

It is in these groups that we encounter a normal, real, power isofix, which keeps the chair and attached to the internal belts of the child. It is in car seats of groups 1 and 0+, he assumes all the energy of the strike in the event of an accident. It is here that he gives all its advantages and in the simplicity of installation and safe.

In car seats of group 1 (9-18 kg)The ISOFIX brackets are usually embedded in the base of the car seat itself (in the M-shaped part).

Although there are a number of models that are simply the top, which is put on the base from the group 0+ (example - Maxi Cosi Pearl et al.).

In the combined car seats of group 0 + / 1 with the system of Isofix (Now there are more and more these) - also built into the base of the car seat itself. But since the chair can be placed both against the stroke, and along the way, then everything is more complicated. Either Isofix is \u200b\u200bused only in the group 0+ (HTS Besafe Izi Combi), or the chairs bowl can be rotated to change the installation direction (Maxi Cosi Milofix). Either generally a turning bowl is 180 degrees, including a passenger landing and disembarking (Romer Dualfix, Cybex Sirona).

What kind of "foot" or focus on the floor on the part of the car seat, which prevents the bag with potatoes in the feet in the child? And what is some anchor strap Top Tether? Maybe better without him?

Isofix is \u200b\u200bessentially a fastening of 2 points on one axis. And it is for this axis that a colossal rotational moment occurs at an accident. In this case, a large load is created on the elements of the ISOFIX system themselves and besides, there is a dangerous shift in front of the chair with a child.
Therefore, it is necessary in the third point of the support. And it happens two types.

First view -retractable focus on the floor in the form of a telescopic "leg" coming out of the base of the car seat. Removes in the floor and thus prevents the rotation and reduces the load on the brackets.

Second view - Anchor mount Top Tether. This is a special belt leaving from top of the children's car seat with a carabium at the end. This carbine is fixed for a special bracket in the car, located, most often, either in the trunk floor, or behind the head restraint of the rear car chairs. This type of fastening is considered universal, all new cars are developed with a place under Top Tether and in the near future, any car will be equipped with them.

Due to the fact that the ISOFIX fastening system assumes huge loads in the event of an accident, ECE R44 / 04 rules are strictly regulated by its application. For this reason, the chairs with the ISOFIX system cannot weigh more than 15 kg, and it can only be used until the weight of the child is 18 kg.

There are separate models that can be attached to ISOFIX without 3 points of support. For example, ROMER VERSAFIX. This is achieved at the expense of the special mobile design of the ISOFIX guides, which allows you to redirect the load down. But this method of fastening is not universal and install the chair in this way you can only make sure that your car is in the list of compatible, attached to the car seat. Justice for the sake, there is probably 95% of all cars.

What then represents "ISOFIX" in children's car seats of groups 2-3 (15-36 kg, from about 3 years)?

The word "Isofix" I wrote in quotes, because the real Isofix system, as already wrote above, does not apply to such a weight of the child at all. Here, there are all sorts of designations "Kidfix", "Sitfix", "Isofit", etc. etc., with which manufacturers emphasize that there is no ISOFIX, but a compatible method of fastening!
In groups of 2-3 (car seats 15-36 kg), the child is already fastened by a regular seat belt conducted through special guides in the car seat. Accordingly, the entire load with an accident is on full belt.
At the same time, the chair should be able to move forward, accompanying the child until the regular seat belt is triggered, providing side protection and proper belt routing during the entire braking. Those. If we secured the chair of the group 2-3 on full-fledged isofix, he would only harm. And of course, no top-tether should not be in the floor here!

Therefore, everything that is called isofixes in a group of 2-3 is simply similar in the installation method, a system that should be able to disassemble, or extend, or shift forward when loaded.

Safety improvement functions Such a system is practically not barred, except that a little limits the displacement during lateral impact. The main advantage - no need to fasten baby car seat The belt, when we are going without a child, well, just worth it - it is more convenient to plant and plant a passenger.

But what about children's car seats from 9 to 36 kg?

What with the so-called "transformers", or as they are often called "universal" chairs of groups 1-2-3?

The most standard customer request "I want a car seat from 9 to 36 kg with a system of Isofix".

So, today, such chairs, at least successfully passed independent tests, there is no in nature. Due to the previously described previously described difference in the design of this ISOFIX group 1 and decorative - from groups 2-3. The first swallow was to become Romer Xtensafix, the decisive of this problem just paying for the relative rotational mobility of the guides. But there came out the problem in the other, and what happened in the plan of "hybrid" isofix, we will not know.

Often, transformers 9-36 kg with safety stands instead of belts fall under the universal trend of the presence of isofix. After all, there is everywhere written - Isofix. But the chip is that the regular belt is skipped through the table, and all the load is again on it, and isofix there again decorative, from group 2-3. Those. In the first group, he simply compensates for the inconvenience of the chair (which without it is not fixed in the car), and in group 2-3 - works, as usual. But its safety does not give its use in this group.

There are still strange examples, like inglesina Prime Miglia I-Fix. Their approach consider completely incorrect. If you carefully read the instructions, then in 1 group (9-18 kg), it is necessary to fix this baby car seat and a regular belt and isofix (i.e., it is simply not clear why the excessive action). And in group 3 - not to use it at all. It is terrible to think how many people did not read in this aforementioned, but simply put a chair on ISOFIX. And the manufacturer, if anything, nothing to say - he warned.

Now the first classic models of transformers 9-36 kg (GR.1-2-3) appear with internal straps and isofix system, which seems to work in all groups. For the most part, from not very well-known manufacturers. I am sure that this problem is technologically solvable, but would refrain from special enthusiasms about such models before at least some official tests confirming the safety of these structures. Isofix for the sake of Isofix I, honestly, I do not understand!

For reference - there is another American version of this system - Latch. The main difference is that there are no rigid metal brackets from the car seat, and there are straps with latches at the ends. In a group of 2-3 differences with similar fasteners of the European modification, no, because It is necessary to hold only the chair.

But with a group of 1 more complicated, because Chairs with this system are not particularly sold in Europe (I suppose, the problem with the oligation of the system itself according to European standards, where everything is rigidly regulated), and therefore, we are unlikely to see independent European crash tests on such chairs. And in the US, tests with the requirements above the standards are carried out only by consumer. Therefore, it remains to believe or do not believe the results of the tests of the manufacturers themselves.

Well, finally, a couple of common ISOFIX myths:

Myth 1. "Car seat with ISOFIX is always safer than without it."
This is not always the case. Firstly, as already understandable from this article, this statement can only be approved for 0+ car seats (0-13 kg) and 1 (9-18 kg). In groups and 3 (15-36 kg), this is not real isofix and does not affect safety. In transformer chairs, it is still either from a group of 2-3, or an unaccificed design and tests design.

But also in groups 0+ and 1, although the armchairs with Isofix most often show top scoresBut also not always and not in all models. For example, in the independent ADAC tests of ADAC 2013 at the base of one of the car seats 0+ Isofix mechanism simply unbuttoned and the chair flew forward as a projectile. And not only on the fastening method depends on the safety of a children's chair, but also from many other factors.

Myth 2. Strictly opposite. "Chairs with Isofix is \u200b\u200bmore dangerous, because Due to the rigid fastening, there is a sharper jerk and a large load on the child. And when attaching a belt, braking occurs more gradually because The belt does not work immediately and besides can stretch a little. "

This is completely incorrect. First, many tests show the opposite. Well, secondly, who is interested, let's figure it out why it is not. When a collision occurs, there is a sharp discharge of speed from the original to zero, over a short period of time. This process is very fast, but not instant, because Some time is the deformation of the car body. And this is good, because Overload from the impact does not occur instantly, with one sharp peak, which we could and not survive, and gradually. Also with a car seat inside. If it is attached to the body is not rigid, then its braking, and therefore, and the inhibition of the child fastened by the inner straps does not begin immediately. It turns out that the child extinguishes its kinetic energy for a smaller time interval than the car body, and gets a much greater peak load, which is just a danger.

For the same reason, the best safety results among chairs with belt fastening, those who have a good strap retasing.

Several conclusions.

• ISOFIX is an excellent invention.
• Its main advantage is to reduce the likelihood of incorrect installation.
• ISOFIX affects safety directly in groups of 0+ and 1 and their combination, in the others - for convenience.
• Not always even in groups 0+ and 1, the availability of ISOFIX gives advantages to safety. It all depends on the design of the chair itself. We look crash tests.
• the search for a full-fledged isofix in the "transformers" 1-2-3 to date is a waste of time. In chairs with a table, it from group 2-3. And in chairs with strap - this is a refusal of verified and safe seats In favor of something non-existent while unknown and unkind.
• Isofixes in groups 0+ and 1 need 3 points of support (except for single modifications). If, say, it is written about the chair that you need a Top Tether belt, and you don't have it in the car - you don't need to take this chair because it is "the best and safe in the world." Get the opposite effect for considerable money. ISOFIX for the sake of isofix is \u200b\u200bthe wrong criterion for choice.

What better isofix or belt, what attachment to give preference? One of the most common issues that potential buyers pay our consultants from once in time. We really hope that this article will somewhat clarify the situation to you and answer all the questions you are interested in.

So, let's start in order, namely with car seat bands 0+ For the smallest, newborn kids.

Immediately it should be noted that the chairs of this group practically never have a built-in ISOFIX mounting system. This is due to the fact that the car seat for newborns is very often used as carrying. That is, the child is usually not removed from the chair at the end of the trip, and the chair is unfastened and together with the baby who lies in the chair as in the basket, leaves the car's salon. Considering this feature, all manufacturers seek to make a group of 0+ groups in the easiest, because a child in 6 months on average weighs about 7 kilograms and the heavier chair, the more hot it becomes.

Isofix. These are metal strips with embedded locks-captures at the end, and the metal cannot but drain the chair.

It is for this reason that the ISOFIX mounting to the chairs of the group 0+ performs a separate element built into the database, or as it also is called the platform for fastening the chair. As a result, it turns out that there is such a base in the car on the ISOFIX loop, and the children's car seat is installed on it. This is definitely more convenient compared to belt fastening, as the chair is snapped on the platform without any effort and just just disgusting from it.

When attaching a car seat on car belt In most cases, it becomes necessary to remove the child from the chair, in order to skip the belts through the guides, and this, you see, not very convenient, especially if the baby is already treated by this time.

And, of course, security, because it is precisely the top priority of a car seat.

Car seats in the group 0+ installed on the ISOFIX platform show higher results in crash tests than the same models fixed by a car belt, and in some cases even significantly improve this indicator.

So if you are allowed tools, we We strongly recommend using the ISOFIX database to install the chairs of the group 0+.

Next Category Car Seat This chair group I.. These chairs are designed for children who have reached 9 months of age, as the kids by this time spend less time on their hands at mom, then the chairs for them do not perform an additional function of carrying, and stationaryly installed in the car. Chairs for children of this age category are sufficiently voluminous and founded. Usually they are installed in the car once and are not taken out of it until the child's growth will reach 1 meter.

ISOFIX for the Armchairs of Group I, as a rule, is built-in option, inseparable from the chair, as the weight of the chair no longer has so much. Since the need to often install and remove the chair is no longer there, the advantage of the simplicity of ISOFIX fastening is somewhat losing its appeal, especially since the process of installing the chair of the group I both on the belt and the ISOFIX approximately the same time consuming. If we consider safety indicators, they differ little in the chairs with an ISOFIX fastening compared to similar models that do not have such a type of fastening.

For example, compare indicators aDAC crash test For 2008, where two models were tested in essence of the same armchair Romer King Plus installed on the belt and the Romer SafeFix Plus having an ISOFIX fastening. As you can see, the indicators are completely identical. And another aspect - the trend of production of the ISOFIX group I is increasingly and more and more that such chairs have the ability to be installed only on ISOFIX. It certainly does not matter if in your car is provided this type Fastenings and you will never go with a child in another car, in which there is no fastening. If you have two cars in your family and in one of them there is no ISOFIX fastening or you do not exclude the possibility of a trip with a child, for example, on a taxi where not all cars are equipped with an ISOFIX fastening system, then better consider the acquisition of a car seat with a belt mounting system, Either try to find chairs that have the ability to be installed both on ISOFIX and on a regular car seat belt, but every year there are less and less such models.

Another feature of the chairs I am the age category with ISOFIX - they are sure must have an additional point of fastening or support. It is necessary to in order emergency situation The chair did not overturned forward.

There are two methods to avoid tipping - fasten the chair in addition to ISOFIX anchor strap or use reference rack. In the first case, the chair has a relatively low weight, takes less space in the car's cabin, because Does not have discover parts, but is not installed in all cars having an ISOFIX fastening. So besides ISOFIX car It must be equipped with an anchor belt mount (for example, in Peugeot 307 such a chair will not be established). A foot-overhead is a bit more volume, has a greater weight and is not very adapted for transportation outside the car (train, aircraft, etc.), but it will be more versatile and well in any car having an ISOFIX fastening.

Summing up, our specialists can summarize the following: the ISOFIX mount for the first age category car seat does not have such a large value as in the group 0+.

Car seats installed on the standard belt are practically not inferior to safety seats with ISOFIX. True, with a little, but important clarification - they must have straps descending systemOnly the presence of this option provides a strong and reliable installation of the chair in the car. Chairs of groups I, equipped with an ISOFIX fastening, are more prestigious and quite expensive. If you have to significantly suffer yourself to the acquisition of car seats with this type of fastening, then it is probably not worth doing this. But it is impossible to say that the ISOFIX fastening in car seats is useless too. It is almost impossible to make mistakes and incorrectly to install a car seat on ISOFIX, and this is a huge advantage.

With a group II-III, intended for older children, everything is much more. A distinctive feature of the automotive seats of this age category is Lack of own built-in belts for attaching a child. For this reason, the main fastening is a car belt, with which the child and chair are also fastened. If you do not have an ISOFIX fastening in the car or if the child rises more often on the front passenger seatwhere Isofix loops usually does not happen, then this is a completely sufficient and full type of fastening. However, if there is an opportunity to install car seats of group II-III using ISOFIX, it is better to use this particular fastening.

What are the advantages, you ask? Everything is very simple, let's see the behavior of the chairs on the crash tests. Chairs that do not have an ISOFIX attachment during the strike start moving forward along with a mannequin until the inertial car belts work. Since the chair has its own, albeit not very high weight, then the load on the mannequin at the points of contact with the belt increases. If the car seat is fixed on ISOFIX, then during the strike it remains motionless to stand on the seat, and automotive belts in this case are caught only the mannequin. Once the weight of the mannequin is not added weight of the chair, then the load at the points of contact with the belt is significantly less. Think, because car seats, designed for adults, do not have the ability to move around the cabin, they are firmly welded and fastened to the car body, and in the case of a sharp braking, the car belt holds only the passenger. It is the principle of fastening and able to provide ISOFIX.

Another question that will ask us buyers who choose car seats of group II-III with ISOFIX is that the ISOFIX fastening cannot withstand the weight of the child exceeding 18 kg. All right weights on which ISOFIX loops are calculatedIn the case of an excessive load there is a risk that the loops may raise. But this is not possible in a situation with the fastening on the ISOFIX car seat of group II-III due to the fact that the weight of the child does not carry any load on ISOFIX, because ISOFIX holds only the chair, the child is holding regular car belts.

Summing up all the above factors, our experts with confidence can say the following: if you have the opportunity to establish a car seat of group II-III on ISOFIX, then, of course, it is better to choose a car seat with this type of fastening.

And finally, a little about the universal chairs of the I-II-III group. Since these chairs combines two types of armchairs - group I and group II-III, the importance of ISOFIX for them is approximately such: during the use of car seat instead of the I age group, the role of ISOFIX has no importance. When the child grows and the car seat begins to be used as a group II-III, the role of Isofix immediately increases at times. After all, all universal chairs, in fact, and there are Armchairs of Group II-III, which is slightly upgraded by adding built-in belts or safety table for the possibility of fastening in the chair of children who have not achieved 1m.
